Description

ワイヤハーネスWire harness
　本発明は、一又は複数の高圧導電路を備えるワイヤハーネスに関する。 The present invention relates to a wire harness provided with one or a plurality of high-voltage conductive paths.
　自動車には、様々な機器が搭載されている。機器には、電気部品や電子部品が数多く設けられている。このような機器同士は、ワイヤハーネスにより接続されている。ワイヤハーネスには、ＥＭＣ（Electro-Magnetic Compatibitity）対策としてノイズフィルタを設けたものが知られている。下記特許文献１には、ノイズフィルタを設けてなるワイヤハーネスが開示されている。 A variety of devices are installed in automobiles. Many electric parts and electronic parts are provided in the equipment. Such devices are connected by a wire harness. A wire harness having a noise filter as an EMC (Electro-Magnetic Compatibitity) countermeasure is known. Patent Document 1 below discloses a wire harness provided with a noise filter.
　特許文献１に開示された従来のノイズフィルタは、自動車に配索されるワイヤハーネスの一部に設けられてノイズを吸収することができるようになっている。具体的には、磁性体の外側に筒状部材を設け、この筒状部材にワイヤハーネスを構成する細い電線を巻回することにより、ノイズを吸収することができるようになっている。 The conventional noise filter disclosed in Patent Document 1 is provided in a part of a wire harness routed in an automobile and can absorb noise. Specifically, a cylindrical member is provided on the outer side of the magnetic body, and by winding a thin electric wire constituting the wire harness around the cylindrical member, noise can be absorbed.
　上記細い電線は、ワイヤハーネスの所定位置から引き出されるようになっている。細い電線は、取り扱いがし易いことから、ノイズフィルタの形成は比較的容易になっている。 The thin electric wire is drawn out from a predetermined position of the wire harness. Since a thin electric wire is easy to handle, formation of a noise filter is relatively easy.
　従来のノイズフィルタには、固定用のクランプが設けられている。クランプは、筒状部材の所定位置に突設されている。筒状部材の両端には、電線固定用の固定部が設けられている。 The conventional noise filter is provided with a clamp for fixing.

　ハイブリッド自動車や電気自動車にあっては、例えばモータユニットとインバータユニットとを接続するワイヤハーネスが高圧のものになることから、高圧のワイヤハーネスの構成として複数本の太物電線が備えられている。 In hybrid vehicles and electric vehicles, for example, since the wire harness connecting the motor unit and the inverter unit has a high voltage, a plurality of thick wires are provided as a configuration of the high voltage wire harness.
　ところで、太物電線の場合、上記従来のノイズフィルタを採用することは困難である。何故ならば、太物電線を小径の筒状部材に巻き付けて所定形状にすることは困難であるからである。また、モータユニットとインバータユニットとの間の配索スペースを考えると、太物電線の場合、より大きなスペースを確保しなければならず、これは困難であるからである。 By the way, in the case of a thick wire, it is difficult to adopt the conventional noise filter. This is because it is difficult to wind a thick electric wire around a small-diameter cylindrical member to obtain a predetermined shape. Also, considering the wiring space between the motor unit and the inverter unit, in the case of a thick wire, a larger space must be secured, which is difficult.
　本発明は、上記した事情に鑑みてなされたもので、ノイズの吸収が可能であり、また、大きなスペースを確保する必要もない高圧のワイヤハーネスを提供することを課題とする。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a high-voltage wire harness that can absorb noise and that does not require a large space.
　上記課題を解決するためになされた本発明のワイヤハーネスは、高圧導電路本体を含む一又は複数の高圧導電路と、前記高圧導電路本体の端末に設けられる端子とを備え、前記高圧導電路本体は、金属線材と絶縁線材とが螺旋状に巻回されて筒状に形成され、交互に隣り合うように位置する前記金属線材と前記絶縁線材は、向かい合う側端面同士が接触している。 The wire harness of the present invention made to solve the above-mentioned problems includes one or a plurality of high-voltage conductive paths including a high-voltage conductive path main body, and a terminal provided at a terminal of the high-voltage conductive path main body, and the high-voltage conductive path The main body is formed in a cylindrical shape by spirally winding a metal wire and an insulating wire, and the metal wire and the insulating wire positioned so as to be adjacent to each other are in contact with each other at their side end surfaces.
　このような特徴を有する本発明によれば、高圧導電路を構成する高圧導電路本体は、高圧の導電路として機能するだけでなく、インダクタとしても機能する構造を有する。本発明は、高圧導電路本体を取り出して、この取り出し部分にノイズフィルタを形成する構造ではないことから、必要最小限の太さのワイヤハーネスにすることができるようになる。本発明において、金属線材及び絶縁線材からなる巻き線部材の寸法を調整することにより、また、巻き線部材の径を調整することにより、インダクタンス値の調整をすることができるようになる。 According to the present invention having such characteristics, the high-voltage conductive path main body constituting the high-voltage conductive path has a structure that not only functions as a high-voltage conductive path but also functions as an inductor. Since the present invention does not have a structure in which a high-voltage conductive path main body is taken out and a noise filter is formed in the taken-out portion, a wire harness having a minimum necessary thickness can be obtained. In the present invention, the inductance value can be adjusted by adjusting the dimensions of the winding member made of the metal wire and the insulating wire, and by adjusting the diameter of the winding member.
　また、本発明のワイヤハーネスは、前記高圧導電路は線状のフェライト部材を更に含み、該フェライト部材は、前記高圧導電路本体の中空部に挿通される。 In the wire harness of the present invention, the high-voltage conductive path further includes a linear ferrite member, and the ferrite member is inserted into the hollow portion of the high-voltage conductive path main body.
　このような特徴を有する本発明によれば、インダクタとして機能する高圧導電路本体にフェライト部材を挿通する構造を有することから、インダクタンス値を高めることができるようになる。 According to the present invention having such characteristics, since the ferrite member is inserted into the high-voltage conductive path main body functioning as an inductor, the inductance value can be increased.
　また、本発明のワイヤハーネスは、前記高圧導電路本体及び前記フェライト部材は、可撓性を有する。 In the wire harness of the present invention, the high-voltage conductive path main body and the ferrite member have flexibility.
　このような特徴を有する本発明によれば、高圧導電路本体及びフェライト部材に可撓性を持たせることから、ワイヤハーネス自身を所望の経路に曲げて配索することができるようになる。 According to the present invention having such a feature, since the high-voltage conductive path main body and the ferrite member are made flexible, the wire harness itself can be bent and routed in a desired path.

For example). Although the wire harness 8 will be described in detail below, the high-voltage conductive path 15 itself functions as a noise filter.
　高圧導電路１５は、導電性を有するとともにインダクタとしても機能する筒状の高圧導電路本体１８と、この高圧導電路本体１８の内部に挿通されるフェライト部材１９と、高圧導電路本体１８の外側に被覆される絶縁体２０とを備えて構成されている。 The high-voltage conductive path 15 includes a cylindrical high-voltage conductive path main body 18 that has conductivity and also functions as an inductor, a ferrite member 19 inserted into the high-voltage conductive path main body 18, and an outer side of the high-voltage conductive path main body 18. And an insulator 20 to be covered.
　高圧導電路１５は、モータユニット３とインバータユニット４とを電気的に接続することができる長さに形成されている。高圧導電路１５は、後述するように金属線材２１と絶縁線材２２とが螺旋状に巻回して形成されていることにより、少なくとも配索等に支障を来さない程度の可撓性を有するように形成されている。 The high-voltage conductive path 15 is formed to a length that can electrically connect the motor unit 3 and the inverter unit 4. As will be described later, the high-voltage conductive path 15 is formed by spirally winding the metal wire 21 and the insulating wire 22 so that the high-voltage conductive path 15 has at least flexibility that does not hinder wiring and the like. Is formed.
　高圧導電路本体１８は、金属線材２１と絶縁線材２２とが所定の径で螺旋状に巻回されて筒状に形成され、且つ、そのようにして巻回されて形成された巻き線部材２３における、交互に隣り合うように位置する金属線材２１と絶縁線材２２は、向かい合う側端面同士が接触している。尚、引用符号２４は隣り合う側端面同士の接触部分を示している。接触部分２４は、上記側端面同士の固着がないような状態で接触している。巻き線部材２３は、螺旋状に巻回する前の状態として、金属線材２１及び絶縁線材２２がそれぞれ線状となるように形成されている（厚みは任意であるものとする）。 The high-voltage conductive path main body 18 is formed into a cylindrical shape by winding a metal wire 21 and an insulating wire 22 in a spiral shape with a predetermined diameter, and a winding member 23 formed by winding in such a manner. In the metal wires 21 and the insulating wires 22 that are alternately adjacent to each other, the side end surfaces facing each other are in contact with each other. Reference numeral 24 indicates a contact portion between adjacent side end surfaces. The contact portions 24 are in contact with each other so that the side end surfaces do not adhere to each other. The winding member 23 is formed so that the metal wire 21 and the insulating wire 22 are each in a linear shape before being spirally wound (thickness is arbitrary).
　巻き線部材２３は、金属線材２１及び絶縁線材２２が異形状となるように形成されている。具体的には、金属線材２１が絶縁線材２２よりも幅広となるように形成されている。金属線材２１は、図１（ｂ）に示されるように、この両側に位置する側部２５が隣り合う絶縁線材２２に向けて三角形状の凸となるようにそれぞれ形成されている。また、絶縁線材２２の側部２６は、該絶縁線材２２の中央に向けて窪む三角形状の凹となるように形成されている（凸、凹の形状は一例であるものとする）。三角形状の凸と凹は、丁度よく嵌り合うように寸法関係が設定されている。 The winding member 23 is formed so that the metal wire 21 and the insulating wire 22 have different shapes. Specifically, the metal wire 21 is formed so as to be wider than the insulating wire 22. As shown in FIG. 1B, the metal wire 21 is formed such that the side portions 25 located on both sides thereof are triangularly convex toward the adjacent insulating wire 22. Moreover, the side part 26 of the insulated wire 22 is formed so as to be a triangular recess that is recessed toward the center of the insulated wire 22 (the convex and concave shapes are examples). The dimensional relationship is set so that the convex and concave parts of the triangle shape fit well.
　高圧導電路本体１８は、以上のような異形状の金属線材２１及び絶縁線材２２を交互の配置で螺旋状に巻回することにより形成されている。高圧導電路本体１８は、金属線材２１及び絶縁線材２２が螺旋状に巻回されて形成されることにより、スプリング効果を有しており、これに伴って可撓性を有している。 The high-voltage conductive path main body 18 is formed by winding the above-mentioned irregularly shaped metal wire 21 and insulating wire 22 in a spiral manner in an alternating arrangement.

The ferrite member 19 is inserted into the hollow portion 27.
　尚、本実施例においては高圧導電路本体１８の形成後にフェライト部材１９を挿通するようになっているが、これに限らないものとする。すなわち、フェライト部材１９の周囲に巻き線部材２３を所定の径で螺旋状に巻回して高圧導電路本体１８を形成し、これによりフェライト部材１９を挿通状態としてもよいものとする。 In this embodiment, the ferrite member 19 is inserted after the high-voltage conductive path main body 18 is formed. However, the present invention is not limited to this. That is, the winding member 23 is spirally wound around the ferrite member 19 with a predetermined diameter to form the high-voltage conductive path main body 18, whereby the ferrite member 19 may be inserted.
　フェライト部材１９は、インダクタンス値を高めることを目的として備えられている。フェライト部材１９は、この全長が高圧導電路本体１８の長さに合わせて設定されている。本実施例のフェライト部材１９は、断面円形状で細長く、可撓性を有するように形成されている。可撓性を持たせるにあたっては、ゴムなどにフェライト粉末を入れて成型する方法や、樹脂材料に金属粉末を入れて成型する方法が採用されている。 The ferrite member 19 is provided for the purpose of increasing the inductance value.

　絶縁体２０は、絶縁性を有する公知の樹脂材料を高圧導電路本体１８の外面に押し出し成形することにより形成されている。絶縁体２０は、所定の厚みに形成されている。 The insulator 20 is formed by extruding a known resin material having insulating properties on the outer surface of the high-voltage conductive path main body 18. The insulator 20 is formed with a predetermined thickness.
　外装部材１６は、上記の如く三本の高圧導電路１５を一括して覆う部材であって、本実施例においては高圧導電路１５の可撓性を損なうことのないシート状のものを巻き付け、そして、テープ等にて巻き付け状態を維持することのできるようなものが採用されている。外装部材１６は、高圧導電路１５を保護することができれば、特に限定されないものとする。 The exterior member 16 is a member that collectively covers the three high-voltage conductive paths 15 as described above, and in the present embodiment, a sheet-shaped member that does not impair the flexibility of the high-voltage conductive paths 15 is wound. And what can maintain a winding state with a tape etc. is employ | adopted. The exterior member 16 is not particularly limited as long as the high-voltage conductive path 15 can be protected.

The cylindrical receiving portion 30 of the inner terminal 28 is inserted into the hollow portion 27 and is electrically connected to the inner surface of the metal wire 21 of the high-voltage conductive path main body 18. The outer terminal 29 crimps the outer end of the high-voltage conductive path body 18 so that the inner terminal 28 and the outer terminal 29 are sandwiched from the inside and outside of the high-voltage conductive path body 18 and come into contact with the metal wire 21.
　図２（ｂ）において、上記二部品は、インナー端子３２及びアウター端子３３から構成される二部品であって、インナー端子３２は、中空部２７に挿入される円筒形状の受け部として形成されている。アウター端子３３には、図示しない接続相手に接続される電気接触部３４と、高圧導電路本体１８の端末外側から加締められる加締め部３５とが形成されている。電気接触部３４は、加締め部３５に連設されている。アウター端子３３の加締め部３５は、加締められて高圧導電路本体１８の金属線材２１の外面に電気的に接続されるようになっている。アウター端子２９が、高圧導電路本体１８の端末外側を加締めることによって、インナー端子３２及びアウター端子３３は、高圧導電路本体１８の内外から挟み込んで金属線材２１に接触するようになっている。 In FIG. 2B, the two parts are two parts composed of an inner terminal 32 and an outer terminal 33, and the inner terminal 32 is formed as a cylindrical receiving part inserted into the hollow part 27.
